Wheels for '98 GLX

I purchased a 98 GLX VR6 six months ago and was thinking about putting different wheels on it. Can any of you suggest a good way to go about finding wheels that look good on the car? I know tirerack.com shows an image of the car and what it would kinda look like with the wheels. I guess I'm just having a hard time deciding what size to get 17" or 18" and what would look the best on my car. My car is silver. If you have any suggestions that would be great. Thanks.

I work at tires plus in colorado.. I have 16" white motegi mr7 wheels on my white jetta.. 17" would work well and look good. A few things you might keep in mind, do you want to lower the suspension?? if you go with 18" wheels yo have to go LOW PROFILE tires which can set you back a pretty pennie, and can get bent EASY.. I have a 2" drop and with 16's they dont rub at all.. alot of people ask me if those are 17"????
So hope that was a little help.. let me know.. And with the finish to be honest its a personal pref, thing,, But I would go with a Machined finish!!!!
